For some perspective, at TI3 7-8th place brought home around 40k. When it's all said and done this year, the same placement will probably this year will probably put out $600k (about what Na'vi got for 2nd place last year).
That's extremely good for the scene. Sure, the people outside of the top 8 will see some restructuring, but that's a positive thing. They under-performed and missed out on a big payoff. They will want to change things up so it goes better next year. If they are successful in reforming, there is plenty of money available in tournaments throughout the year to keep them eating. Not to mention, you need there to be some fluidity so new players can break in. If everything stays too stable, it becomes very difficult for a new good player to land on team that could potentially become a contender.
Conversely, the teams that placed in the top 8 will probably want to keep things as they are to maximize their chances of doing the same thing next year. If they attempt to reform, they risk being left out of the tournament entirely or ending up on worse team. That's a tough sell when you just won over half a million dollars together. The top 8 end up being the veteran teams with history and money, while the bottom 8 become the scrappy contenders.
